Thread which started this ticket: https://issues.redhat.com/browse/SDA-4570?focusedCommentId=18854134&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-18854134

Is Cluster Hibernation now exposed to external customers?

• rh-ee-bchandra commented on 10/9/24"

"We are not productizing hibernation unfortunately due to stability issues hibernation has and other priorities the teams have.
Deleting the cluster that's in hibernating or resuming state must be allowed just how deleting the cluster while installing is allowed."

• Hibernation is currently displayed in the UI with a 'Technology Preview' badge with tooltip and link to https://access.redhat.com/support/offerings/techpreview
• Access is granted via org. level capability key:
  https://gitlab.cee.redhat.com/service/uhc-portal/-/merge_requests/4574 mentions "You need an org which has the "hibernate clusters" capability. OCM UI and Assisted UI have this, at least in Staging."
• Verified in https://gitlab.cee.redhat.com/service/ocm-resources/-/blob/master/data/uhc-stage/orgs/15212158.yaml:

      capabilities:
        - key: capability.organization.hibernate_cluster
          value: "true"

The ask is to enable/disable the 'Delete Cluster' button in the following states:

1. The 'Delete cluster' should be enabled when the cluster is in the status of 'resuming' no matter it has some addon with the external resource or not
2. The 'Delete cluster' should be enabled when the cluster is in the status of 'hibernating/powering down' if it has no addon with the external resource
3. The 'Delete cluster' should be disabled when the cluster is in the status of 'hibernating/powering down' if it has some addon with the external resource

Currently

In the UI the Delete button when 'Resuming' or 'Powering Down' is disabled with a tooltip that reads "The cluster is resuming; wait for it to be ready in order to perform actions" or "This cluster is hibernating; resume cluster in order to perform actions".
